Improvement in gage-cocks



' and packed with india-rubber or other suitable UNITED STATES PATENTOFFICEO IMPROVEMENT IN GAGE-COCKS.

Specification forming part of Letters Patent No. 55,640, dated June 19,186.6.

Be it known that I, C. L. FRINK, ot' Rockville, in the county of Tollandand State ot'l Connecticut, have invented a new and Iin- I provedGage-Cock; and I do hereby declare that the following is a full, clear,and exact description thereof', which will enable others skilled in theart to make and use the same, reference being had to the accompanyingdrawing, forming part of this specification.

The drawing represents a longitudinal eentral section of this invention.A

. This invention consists in the arrangement ot' an elastic and flexibleperforated valve, in combination with the hollow screw-spindle ot' agagecock and with a tapering seat, in such a manner that, by forcing thevalve. down in its seat, the channel in the same is closed and theescape ot' water or steam from the interior ofthe boiler is prevented,and, by moving the valve back from its seat the central channel orpassage in the same is opened and the steam or Water from the boiler istree to discharge. A gate hinged to the handle ot the gage-cock,

To all whom it may concern: 1 f

material, turns down and closes the passage through the center ofthespindle. It' this gate is turned back and the valve is opened, a wirecan be passed clear through the spindle and the valve, and the passageleading to the inieriorof the boiler can be readily and convenientlycleaned.

A represents the body or bulb of my gagecock, which is provided with ascrew-shank, B, to screw into the boiler in the ordinary manner. Thisbulb and shank are bored ont throughout their Whole length receive thespindle C, which is provideddr.;A ith a screwthread, a, to correspond toa thread cut in the outer end ot' the bulb or body A, sothat by turningsaid spindle the valve D,''which is attached to its inner end, is movedtoward and from its seat E.

The valve D is composed of a plug of indiarubber or other flexible andelastic material, e

which is perforated with a central passage, c, to correspond to asimilar passage in the seat and in the spindle. The seat is formed in atube which screws in the inner end ot the body A, as clearly shown in-the drawing, and said seat is tapering, so that the valve, when forceddown into it, is compressed, and the central passage in said valve isclosed.

A handle or button, F, mounted on the outer end ot' thespindle C, servesto turn said spindle and to open and close the valve, and agate, G,which is pivoted to the button bland which is packed on its innersurface with india-rubber or othersuitable material, can be turned downto the position shown in the drawing, so that the saine willclose thepassage through the spindle. When the gate G is turned up and the valveis open a Wire can be passed clear through the central passages in thespindle in the valve and in the seat, and all impurities which mayaccumulate in said passages can be readily cleaned out, so thatthe'gage-cock can be easily kept in good working order.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The flexible and elastic valve D, with a ccntral passage, c, incombination with the conical seat E, spindle C, Iadjustable gate G, andbody A ot' a gage-cock, constructed and operating substantially as andfor the purpose set forth.

The above specification ot' my invention signed by me this 2d day ot'March, 1866.
